MT-01 (Impact/Tranel internal): Zinke +2

I guess Billings is in the second district, but the last time Montana had two U.S House districts thirty years ago, the Western Montana district was fairly Democratic I think because it's more urban (though the urban/rural divide also wasn't as pronounced 30 years ago.)

Western Montana has or had a small contingent of unionized miners, that leaned D.

Still does, that's why Butte-Silver Bow is so Democratic.
